What is Dextrin?
Dextrin is a group of low molecular weight carbohydrates produced by the partial hydrolysis of starch through heat, acid, or enzymatic treatment. The resulting product ranges from white dextrins (produced under milder conditions, more soluble, less coloured) to yellow dextrins (produced under more intense conditions, darker in colour, with stronger adhesive properties). This versatile family of starch derivatives is valued across food, adhesive, and textile industries for its binding, film-forming, and adhesive properties.
Polychem Industries supplies Dextrin in food grade and industrial grade to food manufacturers, adhesive producers, textile companies, and paper industry customers across India and internationally. Its excellent solubility, adhesive strength, and film-forming capability make it one of the most versatile starch-derived products in commercial use.

Applications & Uses
Food Binders & Coatings
Used as a binding agent in food products including snack coatings, breading mixes, and tablet binders for nutritional supplements, providing cohesion and structure while remaining easily digestible.
Adhesives & Gummed Products
One of the largest industrial applications. Dextrin (particularly yellow dextrin) is used as the primary adhesive in gummed paper tape, envelope seals, postage stamps, and corrugated board manufacturing due to its strong, fast-setting adhesive properties.
Textile Sizing & Printing
Used in textile sizing to strengthen yarns during weaving, and as a thickener in textile printing paste formulations, providing the viscosity needed for precise pattern application on fabric.
Paper & Corrugation Industry
Used in paper coating formulations and corrugated board adhesives to bond paper layers together, providing the necessary bond strength for cardboard box and packaging manufacturing.
Pharmaceutical Tablet Binders
Used as a binding excipient in tablet manufacturing, helping hold powder ingredients together during compression while ensuring appropriate tablet disintegration and dissolution characteristics.
Foundry & Casting Applications
Used as a binder in foundry sand core and mould making processes, providing the cohesive strength needed to maintain mould shape during the metal casting process.
